Slewing bearing is a kind of comprehensive load to bear large bearings and can withstand the larger axial and radial load.
Single row cross roller slewing bearing, is composed of two seat, compact structure, high precision, small assembly clearance, for installation accuracy requirement is high, the roller of 1:1 cross arranged, can bear axial force at the same time, the overturning moment and large radial force, is widely used in transportation, engineering machinery and military products.
Slewing ring bearing solutions are ideal for optimal economy in a given envelope dimension; for heavy-duty applications requiring significant load-carrying capacity; for designs where precise positioning is critical; and for the unique requirements of wind turbines.
A turret bearing or slewing ring is a rotational rolling-element bearing or plain bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill. (To "slew" means to turn without change of place.)
Compared to other rolling-element bearings, slewing bearings are thin in section and are often made in diameters of a metre or more; the slewing bearings on the Falkirk Wheel are 4 metre diameter and fit over a 3.5 metre axle. Slewing bearings resemble oversize aircraft control surface bearings.
Slewing bearings often use two rows of rolling elements. They often use three race elements, such as an inner ring and two outer ring "halves" that clamp together axially.
Slewing bearings are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base.
As for other bearings that reciprocate, rather than rotating continuously, lubrication can be difficult. The oil wedge built up in a continuously rotating bearing is disrupted by the stop start motion of slewing. Instead, a hydrostatic bearing with pumped oil flow may be used.

lewing bearings perform extremely well in a variety of applications such as:

• access platforms                                                  • bucket wheel excavators
• conveyor booms                                                    • cranes of all types
• small, medium and large excavators           • indexing tables
• ladle turrets                                                             • offshore applications
• robots                                                                         • railway bogies
• rotary platforms                                                    • stackers
• solar mirrors                                                           • tunnel boring machines
• wind turbines

 Advantages and application:

  The slewing bearing is a basic mechanical component for engineering machinery, mining machinery, construction machinery and other machineries that require relative rotary motions of two parts. The slewing bearing serves to transmit movement, bears load, and connect. However, different from bearing applications, the slewing bearing is generally suitable for low speed and heavy load.
 The slewing bearing has a wide range of applications including engineering machinery, e.g. truck crane, excavator, and tower crane; mining machinery, e.g. bucket wheel machine; metallurgical industry, e.g. clay gun, ladle turret, furnace cover slewing mechanism, etc. It is also used for port machinery, welding machinery, wind power generating equipment, medical equipment, e.g. CT machine, etc. 

Slewing bearing is one of our main products.
1. four point contact ball slewing bearing (no gear, external gear, internal gear);
2. two row ball slewing bearing;
3. crossed cylindrical roller slewing bearing;
4. three row cylindrical roller slewing bearing;
5. crossed tapered roller slewing bearing;
6. ball and roller combined slewing bearing.
With advanced  science and technology, the company develops and manufactures various kinds of  bearing products with inner diameter of over 100 mm according to the national standard,such as large-size and extra-large-size deep-groove ball bearings,angular contact ball bearings,single,double and four-row cylindrical roller bearings,spherical roller bearings,single,double and four-row tapered roller bearings,spherical ball bearings,thrust ball bearings,thrust  roller bearings,slewing bearings,and split bearings,the products are widely used in the fields all over the country, such as port,machine tools,mining,metallurgy,power industry,medical,heavy machinery,coal machinery,cement machinery,petroleum exploration as well as national defence industry.With the right to handle the export.
